Title: Camera focus indicia system
IPC: G03B19/18
Filed: 1973-07-13
Abstract: 1381470 Focus indicator BELL & HOWELL CO 13 July 1973 [31 July 1972] 33571/73 Heading G2A A movable flag visible in the view-finder is coupled with the focusing movement of the lens so that it uncovers one or other of two indicia showing one or two focusing conditions of the lens. In the present case the two conditions are "near" and "far". As shown, the lens barrel 14 can be moved axially, for focusing purposes, within a cylindrical neck portion 15. Light entering through the lens 12 passes through the exposure aperture 16 and is reflected twice by mirrors 24 and 26 to a viewfinder channel 20 and a viewing lens 22. The channel contains an image mask 30 carrying, on a transparent portion thereof, the words "near" and "far". As the barrel 14 moves axially, it bears against a pin 50 which pushes against a spring- loaded rocker arm 52. Arm 52 carries a downwardly projecting flag 55, and because of the arrangement of the optical components of the lens and view-finder systems, the flag blocks off the light rays from passing through either the "near" or else the "far" indicia, so that the one remaining illuminated indicates whether the focus is set for "near" or "far". Fig. 4 (not shown) has a different linkage arrangement between the lens barrel and the flag.

Title: Improvements relating to indirectly heated cathodes
IPC: H01J29/48
Filed: 1960-09-30
Abstract: 958,972. Discharge tubes. PHILIPS ELECTRICAL INDUSTRIES Ltd. Sept. 30, 1960 [Oct. 2, 1959], No. 33638/60. Heading H1D. In an electrode assembly comprising an indirectly-heated, elongated, tubular cathode 1, the longitudinal axis of which extends parallel to the active surface of an adjacent electrode 2, the cathode is secured to an insulating member 8 by means of two metal support strips 3, 4, of low-heat conductivity, which extend parallel to one another at right angles to the longitudinal axis of the cathode, the ends of the cathode being closed. As shown, the strips 3, 4 are integral with cathode tube 1 of a nickel-iron alloy, strips 4 being extended at 5 to close one end of tube 1. Strips 3, 4 are formed with reinforcing ribs 20 and flanges 21 which bear against mica plate 6, and are secured to mica plates 6-8 by brace 9. The arrangement of mica plates 6-8 as shown, increases the leakage path between strips 3, 4 and Wehnelt cylinder 2. Separate screens may be provided to prevent the occurrence of leakage paths between filament supply members 16, 17 and strips 3, 4. Since the nickel-iron alloy of tube 1 is not suitable as a base for emissive layer 12, a further cathode tube 10 of nickel is provided and is formed with a lug 11 to close the other end of tube 1. Alternatively, tubes 1 and 10 may be replaced by a single tube of nickel formed with short legs to which nickeliron strips 3, 4 are welded. A filament current power of 0.5 watts is sufficient. The invention may be used in television receivers, oscillographs, amplifiers or tuning indicator tubes.

Title: Improvements in or relating to control devices for cameras
Inventor: BAUER PETER
IPC: H04N5/225
Filed: 1958-10-22
Abstract: 888,519. Television. PYE Ltd. Oct. 2, 1959 [Oct. 22, 1958], No. 33798/58. Class 40(3). [Also in Group XX] A television camera comprises a control device which includes a crank arm rotatable manually by a knob which is spaced from the axis of said arm, and is rotatably mounted on the crank arm, the rotation of the arm actuating one camera control and the rotation of the knob actuating a second camera control. The Figure shows a device for rotating a lens turret on a television camera and for focusing the lens which is in the operating position. The crank arm 1 and the parts 2, 3 which are fixed to it are attached to a bush 5 rotatably mounted on the camera by means of a nut 4 so that teeth 8 engage. Bush 5 carries a pinion 6 which meshes with a pinion 7 which is part of a lens turret control mechanism so that rotation of the crank arm 1 rotates the turret. A locking means for the crank arm may be provided which operates as follows. A bush 10 is fixed to one end of arm 1 and within this bush two shafts 12, 13 are rotatably mounted; shaft 12 is telescopically slidable on shaft 13 to engage or disengage teeth 12a, 13a, teeth 12a being on a flange 12b. When knob 37 is pressed a pin 36 thereon is moved to the right, thereby disengaging teeth 12a, 13a (because spring 39 keeps shaft 13 in contact with 36), and causes lever 35 to rotate about a pivot 35c so that a locking device on a pin 28 is driven by a spring 29 out of engagement with one of a series of holes in a plate 33 attached to the camera housing and the crank arm 1 can be rotated. Normally springs 40, 39 hold the lever 35 in a position in which pin 28 is in its locking position. The focusing is effected by rotating a handle 14b which is fixed by means of a knob 14 to the shaft 12 so that rotation of handle 14b rotates shaft 12 and when teeth 12a, 13a are engaged, i.e. when knob 37 is released, shaft 13 rotates together with a sprocket 19 which is attached to it. Sprocket 19 is coupled by a chain 20 (other coupling means, e.g. bolts and intermeshing gears are described) to a sprocket 21 which is connected through spindles 22, 26 to a lens focusing means. The diameters of the sprockets are the same so that rotation of arm 1 does not alter the focusing. The knob may be used to control the iris diaphgrams of the lenses. Furthermore, the control device may be used to control the camera remotely by inserting a servo system between the crank arm and knob and the lens and turret control mechanisms. In a modification described in the Provisional Specification the knob 14 is attached directly to the sprocket 19.

Title: Improvements in connection with washing and separating apparatus
IPC: B03B5/62
Filed: 1921-12-20
Abstract: 188,247. Jacquelin, A. Dec. 20, 1921. Addition to 173,501. U p w a r d - c u r - rent classifiers. - An improvement in the washing apparatus described in the parent Specification consists in forming each of the washing funnels into a group of funnels communicating with each other at their lower part and terminating at the upper parts in adjustable overflows independent of each other, so that the mixture treated may be classified into more than two categories in one operation. In the form shown the mixture is delivered from a sizing screen through the feed channel 88 into the funnel 84 where it is exposed to the action of an ascending current 89 the speed of which is greater than the limit speed of the lightest products of the mixture. The latter are therefore carried away by the current and discharged through the overflow 86. The heavier products continue to fall until they reach the extension 83 where they meet a current 90 of greater velocity. A further separation takes places, the next lightest products being carried by the stream 91 up the funnel 85 to be discharged through the overflow 87. A similar separation takes place in the current 93 in the conduit 80, the third lightest particles 'being carried by the current 92 up the funnel 81 to be discharged through the overflow 82, whilst theheaviest particles of all are collected from the bottom of the conduit 80. Any number of washing funnels may be used and they may be cylindrical with cylindrical overflows, or placed back to back and either on the same or opposite sides of the feed channel.

Title: Circuit arrangement for identifying code words
IPC: H04W88/02
Filed: 1975-08-21
Abstract: 1518685 Selective signalling PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 21 Aug 1975 [24 Aug 1974] 34781/75 Heading G4H In a circuit arrangement for identifying a series of unknown code words, a succession of parallel (reference) code words is read from each of two stores in turn, these words being serialized and then compared with the unknown code words to be identified. In a mobile radio telephone station, a multidigit call number is received followed by channel selection digit(s), each digit preceded by a start signal which starts a first clock pulse generator to produce a number of clock pulses equal to the number of bits in the digit. The clock pulses advance a counter once per digit to address a first store to read out the station's call number, serial by digit, parallel by bit, to a serializer (code converter) which converts each digit to serial by bit form, in which form the digits are compared with the received call number, the comparator resetting the counter on inequality. The clock pulses also go to the serializer and comparator. If the whole call number is equal, the comparator starts and controls a second clock pulse generator to supply the digits 0 to 9 in coded form from a second store, in turn, each digit parallel-by-bit, the digits being serialized in the serializer and then compared in the comparator with the (or each of the, in turn) channel selection digit(s), to obtain a match. The coding is such that this can be done by comparing the first incoming bit with the first bit of each digit from the second store in turn until equality is found, then comparing the second incoming bit with the second bit of the digit thus reached in the sequence 0 to 9, and subsequent digits, until equality is found, and so on for the remaining bit positions, the comparator controlling the second clock pulse generator as appropriate. The digit(s) in the second store thus reached is/are stored in a third store and used to select a channel. The station call number is sent as an acknowledgment as a frequency-modulated signal on the voice channel carrier, using the first clock pulse generator, counter, first store and serializer.

A conduit end fitting 32 comprises an openended hollow body having an annular recessed portion 66 axially spaced from the open end, a cylindrical locking surface 72 between the recess and the open end of a diameter less than the diameter of the recess and a radially expansible ring 84 within the body having a normal outer diameter equal to that of the locking surface and axially movable within said bore between alignment with the locking surface and alignment with the recess, first and second abutments limiting axial movement of the ring between the recess and the locking surface. As shown, the fitting is in two parts 34, 36 the part 34 adapted for engagement with fluid system components, and the part 36 having a thin annular sleeve adapted to receive the part 34 and be swaged around the part to couple the portions together A recess between the two parts holds a sealing ring 60 serving as a seal for a spring-loaded valve 76 situated in the part 34. The part 36 contains the locking surface 72 the recess and the ring and carries a U-shaped sleeve 88 the inner limit 90 of which acts as an abutment for the ring when situated adjacent the locking surface and also serves to release a pipe when locked in the bore. A shoulder 68 adjacent the recess acts as the other abutment. In use a pipe spigot (Fig. 1) provided with a projection 18 having inclined forward 20 and rear 22 sides with a cylindrical top 24 is inserted in the bore, the end portion of the spigot serving to open the valve and seal against the sealing ring 60 while the tapered face 20 causes the ring 84 to expand. The ring 84 then slides over the surface 24 and contracts behind the protrusion 18 and the spring- loaded valve tends to force the spigot out of the bore until the ring 84 reaches the abutment surface of the sleeve 88 whereon the locking surface 72 prevents expansion of the ring and thus the spigot is locked within the bore. The spigot is released by moving the spigot and the sleeve 88 to the right, as shown in Fig. 2, to position the ring 84 adjacent the recess to enable the ring to be expanded by tapered face 22.

Abstract: 343,170. Thermionic modulators. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, and WELLS, N., 32, Richmond Park Road, Sheen, both in London. Nov. 16, 1929, No. 35108. [Class 40 (v).] In a modulating system of the kind in which a resistance is common to the HT supply circuits of a modulating valve and a high-frequency valve, as in Specification 245,829, [Class 40 (v), Wireless signalling &c.], a condenser is connected between the plate and filament of the modulating valve. As shown, a keying-relay 4 operates to connect a tone generator 1 across the grid circuit of a valve 9, which is resistance-coupled to the main modulating valve 16. Resistance 19 in the plate circuit of this valve is also included in the plate-supply circuit of a carrier-wave generator or amplifier so that voltage variations across resistance 19 modulate the amplitude of the carrier wave. The grid of the amplifier 9 is negatively biased by battery 11 through a high resistance 6, and the tone frequency is applied to the grid through a condenser 2 when the relay tongue 7 makes contact at 3. The essential feature of the invention is the provision of a condenser 14 of capacity À05 to À1 mf. between the plate and filament of the valve 9. Its pressure causes the radiation to occupy a larger percentage of the marking period of the signal; and the percentage modulation may be varied by adjusting the condenser.
